Members of phylum Arthropoda have segmented bodies, external skeletons, jointed appendages; have rigid body structures made mostly of bio-mineralized alpha-chitin. They must shed their exoskeleton in order to grow. They have repeated body segments with leg or appendage pairs, ventral nerve cords with paired ganglia in each segment. They are bilaterally symmetrical with compound eyes and an internal body cavity with an open circulatory system.
Spiders have 8 legs and 2 body parts.
